FOR BEST ACCURACY

The Chlorine+ eXact® EZ photometer has a 5 minute auto-shutoff timer.

Each test menu can store 20 results. To retrieve the stored results, go to the desired test using the MENU key. When the desired test is displayed, press and hold down the MENU key. Continue holding down the MENU key to scroll the stored results for that test, starting with the most recent result. The meter will display, from memory, the last 20 readings in sequence beginning with -20, which is the latest result, followed by -19, which is the 2nd latest result, etc; and fi nally -01, which is the oldest result retained. Only the last 20 readings are stored in each menu. This meter is able to store 100 results in memory (20 in each menu).

Before testing, rinse the meter sample cell with the sample water 3 times.

Always fi ll the cell to capacity (4mL); be careful not to splash liquid over the side.

Test immediately after fi lling the cell with the water sample.

Due to the strip slitting process, you may fi nd one or two strips that are noticeably smaller or larger in width than the normal strips in the bottle. These should be discarded. Using these strips may give unreliable results.

When testing pH, it is recommended to run the pH test prior to running Chlorine. If you choose to run the pH after Chlorine, ensure you thoroughly clean the cell with water and the brush provided.

Meter is not compatible for use with powder pillows, tablets, or liquids from other manufacturers.

Dip strip for entire countdown.

Even if all pads are not immersed in water, DO NOT BEND THE STRIP. Make sure the strip touches the bottom of the CELL while dipping the strip for 20 seconds.

Each eXact® Strip Micro is valid for ONLY one test. Discard strip after use.

Dry the outside of the meter and inside the mixing cap before storage to prevent corrosion.

Remove batteries before storing for prolonged periods.

Store the meter and test materials out of direct sunlight and away from chemical storage areas.

Minimize exposure of meter and test reagents to heat above 80°F (27°C).

When installing batteries, verify the O-ring is still attached to the screw before tightening.

If water temperature is above 95°F/35°C, press READ when the timer displays “10” for Total Bromine, Free Chlorine, Total Chlorine, and pH tests.

Cleaning the cell with water and brush after each test is recommended for best accuracy and prior to storage of unit.

The Chlorine+ eXact® EZ has been factory calibrated and will stay valid because of its exceptional quality. We are so confi dent in the Chlorine+ eXact® EZ, we offer an industry leading 2-year warranty.

We built the Chlorine+ eXact® EZ to be easy, accurate and environmentally friendly. We have achieved this by utilizing our patented eXact® Strip Micro Technology, which uses 60% less water and chemistry than alternative methods. Instead of using a 10mL water sample, eXact® Strip Micro uses a 4mL water sample. The accuracy of the meter is maintained by designing the sample cell with an 11mm path-length.

ABOUT

COMPLIANCE TESTINGThis DPD test system for Chlorine and Chlorine Dioxide are accepted for reporting by most health departments because the tests are USEPA (DIN Standard 38 408 G4/G5, ISO 7393/2) accepted for testing requirements for Free Chlorine, Total Chlorine, and Chlorine Dioxide.

The compliance requirement is a photometer wavelength to measure between 490 and 530nm. The Chlorine+ eXact® EZ smart photometer uses a 525nm wavelength and 11 mm path-length. The eXact® Strip Micro CL/Cd (DPD-1) use the same reagents and proportions, and the resulting solution pH is maintained between 6.2 and 6.5 as specifi ed by AWWA method 4500-Cl G/ClO2-D. The USEPA does not “approve” commercial DPD delivery systems. The eXact® Strip Micro CL (DPD-1) for Free Chlorine, the eXact® Strip Micro CL (DPD-4) for Total Chlorine, and the eXact® Strip Micro Cd (DPD-1) for Chlorine Dioxide meet your reportable testing requirements because the eXact® Strip Micro strips deliver the same chemicals in identical proportions. Consult with your local health department for offi cial regulations.

MODEL AQUATIC HEALTH CODEAND NSF/ANSI 50 CERTIFICATION

The Model Aquatic Health Code (MAHC) is a set of guidelines published by the Centers for Disease Control and Prevention (CDC). This document brings together the latest knowledge based on science and best practices to help state and local government offi cials develop and update pool codes. They may use the code in whole, choose to use parts, or modify to fi t their needs. Use of the MAHC is intended to save time and resources spent individually developing and updating codes across the country, while giving agencies the benefi t of the latest science and best practices to help keep pools fun, safe, and healthy.

The MAHC requires NSF/ANSI 50 certifi cation of water quality testing devices (WQTD) used in recreational facilities such as public swimming pools, interactive fountains, and Water parks. Third-party certifi cation to NSF/ANSI 50 allows manufacturers to make verifi ed claims regarding the performance, accuracy and operating range of their WQTD. The performance testing of a WQTD involves accuracy and repeatability testing on two different lots of new production. Unlike most NSF/ANSI 50 certifi cations, WQTDs require follow-up testing of the product at the end of the manufacturer’s specifi ed shelf life. Certifi ed products are given an accuracy rating to one of three levels: L1, L2 or L3, with L1 being the highest accuracy rating.
